You should read these Important Safety Instructions

Keep these instructions in a safe place

Before using your JM4 Looper, carefully read the applicable items of these operating instructions and the safety suggestions.

1. Obey all warnings on the amp and in the JM4 Looper Manual.

2. Connect only to AC power outlets rated 100-120V or 200-240V 47-63Hz (depending on voltage range of the power supply; refer to label on the unit).

3. Do not perform service operations beyond those described in the JM4 Looper Manual. Service is required when the apparatus has been damaged in any way, such as:

 • power-supplycordorplugisdamaged

 • liquidhasbeenspilledorobjectshavefallenintotheapparatus

 • theunitisdroppedortheenclosureisdamaged.

4. Transformers can get hot during operation. Do not touch during operation or shortly after.

5. Do not place near heat sources, such as radiators, heat registers, or appliances which produce heat. Keep the rear of the unit at least three inches from walls or other items that might block heat radiation.

6. Do not block any of the ventilation openings or use in an enclosed space.

7. Guard against objects or liquids entering the enclosure. Do not use or place unit near water.

8. Do not step on power cords. Do not place items on top of power cords so that they are pinched or leaned on. Pay particular attention to the cord at the plug end and the point where it connects to the amp.

9. Unplug the amp when not in use for extended periods of time. Unplug the amp during lightning storms.

10. Clean only with a damp cloth.

11. Do not defeat the safety purpose of the grounding type plug. A grounding type plug has two blades and a third grounding prong. The third prong is provided for your safety. When the provided plug does not ﬁt into your outlet, consult an electrician for replacement of the obsolete outlet.

12. Only use attachments/accessories speciﬁed by the manufacturer.

13. Prolonged listening at high volume levels may cause irreparable hearing loss and/or damage. Always be sure to practice “safe listening.”
